1. Ke Kaʻa Kaʻa Kaumaha ʻEmi Hou
Duplex waiwai, ikaika kiʻekiʻenā pā kila kilaa ua hoʻokō maikaʻi ʻia nā papa pākaukau i nā kaʻa kaʻa koʻikoʻi o ka ikehu hou, me ka hoʻoponopono ʻana i nā pilikia ʻino a me ka luhi i ʻike ʻia e ke kila kalapona kuʻuna i ka haʻahaʻa haʻahaʻa a me nā kaiapuni kahakai. ʻOi aku ka ikaika o kona tensile ma luna o 30% kiʻekiʻe ma mua o ke kila Q355 maʻamau, a ʻoi aku ka ikaika o kona hoʻoulu ʻana ma luna o 25% kiʻekiʻe. Loaʻa iā ia kahi hoʻolālā māmā, hoʻonui i ke ola o ka pahu a me ka hōʻoia ʻana i ka pololei o ka pahu pākaukau i ka wā o ka hoʻololi ʻana. Ma kahi kokoke i 100 mau kaʻa kaʻa kaumaha ma ka ʻāina ʻoihana kahakai o Ningde no 18 mahina me ka ʻole o ka deformation a i ʻole ka ʻino. He ʻumikūmālua mau kaʻa kaumaha i hoʻolako ʻia me kēia pahu i lawe ʻia aku i waho no ka manawa mua.

2. ʻO ka mālama ʻana i ka ikehu hydrogen a me nā lako kaʻa
ʻO Jiugang's S31603 (JLH) austenitic stainless steel, i hōʻoia ʻia e ka National Special Inspection Institute, i hoʻolālā pono ʻia no ka hoʻohana ʻana i ka wai hydrogen/liquid helium (-269 ° C) cryogenic pressure vessels. Mālama kēia mea i ka ductility maikaʻi, ka paʻakikī o ka hopena, a me ka haʻahaʻa haʻahaʻa i ka hydrogen embrittlement a hiki i nā haʻahaʻa haʻahaʻa loa, e hoʻopiha ana i kahi āpau i nā kila kūikawā ma Northwest China a me ka hoʻolaha ʻana i ka hana ʻana i nā pahu mālama wai hydrogen i hana ʻia ma ka home.

3. ʻOihana Hoʻonaʻauao Nui

Ke hoʻohana nei ka papahana hydropower o ka muliwai ʻo Yarlung Zangbo i ka 06Cr13Ni4Mo haʻahaʻa-carbon martensitic stainless steel (pono kēlā me kēia ʻāpana he 300-400 tons), me ka huina i manaʻo ʻia he 28,000-37,000 tons, e pale aku i ka hopena o ka wai kiʻekiʻe a me ka ʻino o ka cavitation. Hoʻohana ʻia ke kila kila duplex waiwai i nā hui hoʻonui alahaka a me nā kākoʻo hoʻouna e kū i ka haʻahaʻa kiʻekiʻe a me ka corrosive kaiapuni o ka pāpū, me ka nui o ka mākeke o ʻumi mau piliona yuan.

4. Hale Paa a me na Hana Hana

ʻO nā pā pale hoʻolālā (e like me ka Hale Hōʻikeʻike o Shanghai), nā mea hoʻoheheʻe kemika (316L no ka pale ʻana i ka corrosion crystal), a me nā mea hana lāʻau lapaʻau (electrolytically polished.304/316L) hilinaʻi i ke kila kila no kona kūpaʻa ʻana i ka wā, ka maʻemaʻe, a me nā mea hoʻonaninani. Hoʻohana nā lako hana meaʻai a me nā linings (430/444 steel) i kāna mau mea maʻalahi i ka hoʻomaʻemaʻe a me ke kūpaʻa ʻana i ka chloride ion corrosion.
